CT Receptors on Osteoclasts

Question

CT receptors on osteoclasts
A) Operate through a Gs mechanism
B) Signal through a Gq-coupled receptor
C) Seal off an area by binding to osteocalcin
D) Require 1,25 dihydroxycholecalciferol for activation
E) Activate bone resorption

Accepted Answer

Calcitonin (CT) receptors on osteoclasts operate through a Gs protein-coupled mechanism, which leads to the inhibition of osteoclast activity and bone resorption.
